To all whom t may concerm- Be it known that I, VILLIAM LUND, a subjectof the Queen of Great Britain and Ireland, and a resident ofPhiladelphia, Pennsylvania, haveinvented certain Improvements inWool-Combing Machines, of which the following is a specification.

My invention consists of improvements in that class of wool-combingmachines of which the Noble machineis an example,and in which the fiberto be combed is pressed into the teeth of a fixed ring and a revolvingring by means of a reciprocating dabbing-brush.

The objects of r'my invention are to equalize the wear upon thebrush-reciprocating devices and to simplify and cheapen the constructionof the same and of the brushes.

In the accompanying drawings, Figure 1 is wool-combing machine toillustrate my invention; Fig. 2, a front view, partly in section, andFigs. 3, 4, 5, and 6 detached views of parts of the machine,illustrating features of construction.

V.A represents part of the lixed frame of the machine; B, part of thehollow steam-heated ring, and D, part of one of the inner rings of themachine, both of these rings having proj ecting teeth ct upon the top,andthe parts rbeing otherwise constructed as usual in ma chines of thisclass.

Secured to theframe'A is a column or standard, F, which carries thebearings for the brushreciprocating devices.

The dabbing-brush is made in two sections, G G, each having a stem, b,and these stems are guided in sleeves or boxes d at the outer ends ofupper and lower arms, f, the latterbeing secured to and projecting fromthe column or standard F. The upper armsfcarry bearings g for theoperating-shaft I, which has a pulley, h, for receivinga driving-beltfrom any suitable counter-shaft, said shaft I being retained in positionlongitudinally by means of collars It. Y.

Keyed or otherwise secured to the shaft I is a disk, H, and secured toor forming part of this disk are two eccentricsJ J, set opposite to eachother-that is to say, on opposite sides of the axis of the shaft-thestrap K of one eccentric being connected to a collar, z', on the stem bof one of the brush-sections G, and the strap of the other eccentricbeing likewise connected to a similar collar on the stem of the otherbrush-section, so that as the shaft I is rotated a reciprocatingmovement will be imparted to both sections,vone rising as the otherdescends.

Plates m, secured to the`eccentrics, overlap.

the eccentric-straps K, and prevent the accidental detaching of thesame, and the collars t are confined between nuts n on threaded portionsof the stems b, whereby said stems and the brush-sections carriedthereby can be adjusted vertically, as desired.

In order to permit ready adjustment of the brush-sections and theirready application to or removal fromthe operating-stems b, each of thelatter carries at the lower end a grooved plate, M, for the reception ofribs w on .the back of the brush-block N, these ribs forming an undercutslot, p, for the reception of thel mechanism for operating a Ysingledabbing-V brush, the eccentrics being set opposite to each other, sothat one brush descends as the other rises. The brushes thus actalternately upon the wool at opposite sides of the machine; hence the:strain comes first upon one end of the long operating-shaft and thenupon the opposite end,.thus tending to interfere with the steady drivingof said shaft, andto cause torsional strain, to counteract which theshaft must be made excessively heavy. In carrying out my invention,therefore, in place vof single dabbing-brushes at each side of the ma-ychine, I use the dabbingbrush made in sections, acting alternately, asdescribed, so that the strain upon each section is reducedto onehalf ofwhat it would be upon the whole brush, and brush-sections at each sideof the machine are acting simultaneously. Even if a` singleoperatingshaft for the brushes at both sides ,of the machinewere used,therefore, the strain upon the opposite ends of said shaft would be IOOequalized. For operating the brush-sections of my improved machine,however, the short shafts, each carried by bearings upon one of thepillars of the machine, and each having the operating eccentricscentrally-arranged thereon, as shown and described, are preferred, assuch short shafts are more economical than the single long shaft,because their aggregate length is less, and because the two ecccntricsform practically one structure, so that they cannot cause uneven strainon the shaft, which, in consequence, can be made lighter than the singlelong shaft. By my invention, also, I am enabled not only to equalize thewear of the parts which operate the brushsections, but I am also enabledto cheapen the latter, as the small sections which I use are mnchlessexpensive than thesingle large brush heretofore employed. Moreover, whenthe irst brushsection becomes worn it may be renewed without renewingthe second brush-section; or the latter may take the place of thefirst,and a new second section may be supplied. By first brushsection77l mean that section which rst acts upon the wool enteringr the machine,this being usually the right-hand section shown in the drawings.

It will be evident that crank-pins on the shaft I may be used in placeof eccentrics, if desired; but the ecccntrics are preferred.

I claim as my invention- 1. The combination of the toothed rings of acombing-machine with a dabbing-brnsh composed `of sections working sideby side and with means for reciprocating said sections, whereby they arecaused to act alternately, all substantially as specied.

2. The combination of the column F of the machine, a dabbing-brushcomposed of sections located side by side, ashort driving-shaft havingbearings carried wholly by said column, eccentrics on said shaft, andmechanism, substanti ally as descrfibeclvhereby the movement of saideccentrics is imparted to the sections of the dabbi ng-brush, allsubstantially as specified.

8. The combination of the dabbing-brush, composed of sections locatedside by side, a driving'shaft, a pair of eccentrics forming a singlestructure,means for securing said structure to the shaft, and mechanismwhereby the movement of the eccentrics is transmitted to the sections ofthe dabbing-brush, all substantially as specified.

4. The combination of the stem liavinga grooved plate at the lower end,the slotted brush-block having a portion adapted to said lgroove, andconfining bolts and nuts whereby the brush-block is secured to theplate, all snbstantially as specified.

In testimony whereof I have signed my name to this specilication in thepresence of two subscribing witnesses.
